A production process of foam concrete sandwich color steel wallboard

Abstract

The invention provides a foam concrete sandwich color wall steel plate and a production technique thereof. The foam concrete sandwich color wall steel plate comprises a first steel plate layer, a second steel plate layer, a cement paste layer, a first foam concrete layer and a second foam concrete layer, wherein the first steel plate layer and the second steel plate layer are parallel; the cement paste layer is located between the first steel plate layer and the second steel plate layer; the space between the first steel plate layer and the cement paste layer is filled with the first foam concrete layer; and the space between the second steel plate layer and the cement paste layer is filled with the second foam concrete layer. The production technique comprises the steps of die-filling, pouring, die disassembling, combining, forming and the like. The foam concrete layers are adopted as a sandwich material and are not prone to combustion, and compared with traditional sandwich materials, the foam concrete layers are relatively hard and not prone to aging, the fracture resistance is relatively good, and the service life is relatively long. In addition, the foam concrete layers and the cement paste layer are used as the sandwich material, the effect that the sandwich color wall steel plate has the strength as traditional EPS composite wallboards is ensured, and no toxic gas is emitted at high temperatures.

Description

technical field [0001] The invention relates to a prefabricated board for building and its production process, in particular to a foam concrete sandwich color steel wall board and its production process. Background technique [0002] Sandwich color steel wall panel is a new type of enclosure structure panel integrating load bearing, heat preservation, waterproof and decoration. It is widely used in various buildings such as industrial workshops, public buildings, composite houses, and purification projects. [0003] Traditional sandwich color steel wall panels usually use color-coated steel as the surface material, self-extinguishing polystyrene, polyurethane, glass wool or rock wool as the core material, and are pressurized and heated in a continuous molding machine with thermosetting adhesive. It is an ultra-light building board made of solidification, trimming, grooving, blanking and other processes. Among these core materials, only rock wool and glass wool are non-combus...

AI Technical Summary

Problems solved by technology

[0003] Traditional sandwich color steel wall panels usually use color-coated steel as the surface material, self-extinguishing polystyrene, polyurethane, glass wool or rock wool as the core material, and are pressurized and heated in a continuous molding machine with thermosetting adhesive. It is an ultra-light building board made of solidification, trimming, grooving, blanking and other processes. Among these core materials, only rock wool and glass wool are non-combustible materials, and other sandwich materials are used in color steel sandwich panels. It is very easy to cause fire when used. At the same time, because the steel plate of the traditional sandwich color steel wallboard is usually a flat structure, the sandwich material is usually soft material, and the flexural performance is relatively poor.

[0004] In addition, the inner and outer layers of the transmission sandwich color steel wall panels are produced separately and then combined into sandwich color steel wall panels. Many sandwich materials are often produced for a long time before being applied to sandwich color steel wall panels. When combining, special treatment is required to ensure the tightness of the combination, and if the production time of the sandwich material is too long, it is easy to age, which will affect the service life of the entire sandwich color steel wall panel
